RADIATOR SHUTTER.

Application area April a1, 192e.

Anobject of this invention is to provide cheap, simple and effectivemeans tor regulating the temperature of internal combustion motorshaving radiators.

In the invention I provide at one end ot the radiator a spring take-upcurtain roller with curtain wound thereon, in which the spring bracketsorn the roller are mounted at one margin ot one end of the radiator insuch position that when the curtain is drawn out or extended, it willclose the ends ot cellular openings and obstruct the flow of air throughthose of the radiator tubes thus covered; and I connect with the bar otthe curtain, flexible means leading to position for control by thedriver ot the engine, so that by drawing the connection the curtain maybe adjusted across the open ends of some or all of the radiatorcellular' openings, and by releasing the connection, the curtain will berewound on the roller, thus allowing air to flow freely through to coolthe radiator more or less, depending on the number of cellular openingsleft Jfree.

The curtain may be applied at either end of the radiator and theconnection which is adjusted may be held in adjusted position bysecuring it to the dash board or other convenient part of the vehiclewithin convenient reach of the driver.

In carrying out the invention I have mounted the spring take-up' rollerat the lower margin of the iront end ot the radiator and have run theflexible connection from the curtain bar up in front of the radiator andthrough the upper part of tubes on opposite sides of the top of theradiator, but it is understood that the curtain roller may be journalledat front or back ot the radiator and at top, bottom or sides of theradiator as preferred by the constructor.

Further objects of the invention are cheapness, compactness andsimplicity ot construction, ease of application, and convenience ofoperation.

Other objects, advantages and features ot invention may appear from theaccompanying drawing, the subjoined detailed description and theappended claims.

The accompanying drawing illustrates the invention.

Figure 1 is a perspective view of a device embodying my inventionapplied to the front end of the radiator of an automobile, a traction ofwhich is shown.

Serial No. 103,421.

Fig. 2 is an enlarged fragmental detail partly in section.

Fig. 3 is a fragmental detail on a yet larger scale of the parts shownat the lower lettcorner of Fig. 2. The radiator cellular openings areomitted.

The radiator 1 of an automobile a is shown provided on the front endwith a curtain 2 mounted on a spring operated take-up roller 3 the endsof which are mounted in brackets 4, 5, which are attached at the sideedges of the radiator in such manner that the roller extends across thelower end thereof so that when the curtain 2 is drawn up a greater o-rless extent it will cover the outer ends of the radiator cellularopenings to a greater or less degree as may be desired to restrict theflow of air through the radiator cellu la'r opennigs.

Guide wires 6 are attached at one end to the base of the brackets 4, 5,and the other ends are attached to the upper end of the radiator,preferably being stretched taut and wound about the outer end ot tubes 7as indicated in Fig. 3.

The curtain is raised or lowered by means of wires, cords or othersuitable flexible connection 8 attached at either end oi the cur tainbar 9, carried through the tubes 7, and the hood 10, and through thedash board 11 to a drum 12 which is in easy reach ot and operable by thedriver` (not shown).

The tubes 7 are held in place by means of nuts 13 screwed onto thethreaded ends of the tubes 7 and the journal brackets 4, 5 are attachedby means of bolts 14 inserted through tube 7 and held by nuts 15, andfelt and metal washers'lG, 17 to protect the surface of the radiatorfrom being marred by the bolts and nuts 14, 15 and brackets 4 and 5.

A housing 18 protects the roller 3 and the curtain rolled thereon and isheld in place by the bolts 14 which also attach the brackets 4 and 5 tothe radiator.

The outer surface of the curtain is preferably marked as at 19 tosimulate the front of the radiator and thereby render it lessconspicuous.

I claim 1. In combination with an automobile radiator; of tubes disposedin the upper and lower ends of said radiator; bolts extending throughthe lower of said tubes; brackets secured to the base of said radiatorby said bolts; revvinding roller journalled in said brackets; a curtainsheet arranged to Wind nected to the radiator by said bolts; a re-Winding roller journalled in said brackets; a curtain arranged to Windupon said roller and adapted for movement vertically along t-he front ofthe radiator; cables connected to the free end ofsaid curtain andadapted for passage through the uppermost tubes and Wires connected tosaid brackets and upper tubes for guiding said curtain.

In testimony whereof, I havehereunto set my hand at Los Angeles,California, this 24th day of March, 1926.
